Described is a marine science course offered to high school biology teachers. The course objectives were designed to introduce teachers to a marine science subject that could be used in the secondary science classroom and laboratory and to create an awareness of the issues surrounding the marine sciences. (DS)

Activities and instructional strategies for two multigrade lessons are provided. Activity objectives include describing an artificial reef (such as a sunken ocean liner) as an ecosystem, knowing animal types in the ecosystem, and describing a food web. (JN)

Presented are the abstracts from three research projects involving deep sea technology which were a part of a marine science symposium. Five sets of activities on deep sea science are included, one each for grades K-2, 3-5, 6-8 and 9-12, and informal education. (CW)

Presented are the abstracts from three research projects on marine social systems which were a part of a marine science symposium. Five sets of activities on marine animal communication are included, one each for grades K-2, 3-5, 6-8 and 9-12, and informal education. (CW)

The habitat, life history, feeding, classification, anatomy and pearl production of the American oyster (Crassostrea virginica) are presented. A list of other oyster reef inhabitants and predators is provided. Harvest and habitat loss are discussed. (CW)

Presents two lesson plans for: (1) a long-term project where students use simple materials to investigate a nearby aquatic habitat; and (2) hay infusions (jars with water and hay), one of which receives a plant fertilizer. (DH)

Described are one-atmosphere and compressed-gas technologies used for investigating the environment beneath the surface of the ocean. Suggestions for teaching this information to high school students are provided. (CW)

Described is a teacher education program organized by the Sea Education Association in Woods Hole (Massachusetts). The experience, including activities and examples of studies conducted, is discussed. Contact information for future cruises is included. (CW)

Discussed is the importance of marine education and experience with the seashore in helping children to adopt positive attitudes about nature. (CW)

Provides awareness information on the sources, types, and serious effects on wildlife of nondegradable materials which are causing local as well as global problems. Discusses current ways the problem is being attacked and educational implications for environmental programs. (RT)
